The use of plant extract in the phytosynthesis of nanoparticles can be an eco-friendly approach and have been suggested as possible alternative to conventional method namely physical and chemical procedure. In the present research, all the chemical reagents were of analytical grade and used without further purification in these experiments. A conventional heating phytosynthesis route by using Fumaria Officinalis was used to produce the Ag nanoparticles. The radical scavenging activity test was used to check their anti-oxidant activities using 2,2-diphenyl-1-picrylhydrazyl (DPPH). The morphological properties and particle size of synthesized Ag nanoparticles have been confirmed by Scanning Electron Microscope (SEM-EDX), Fourier transform Infrared (FT-IR) and Dynamic Light Scattering (DLS). The synthesized nanoparticles were characterized by XRD for the crystallinity, phase purity and average particle crystallites size. Based on FT IR results the OH groups are responsible for reducing and capping of Ag cations. The increase in the intensity of carbonyl group confirms this issue. Moreover, the synthesized nanoparticles possess a range of diameter between 30-40 nm according to the results of SEM. Antibacterial activity against L.monocylogenes, L.monocytogens and E.coil were investigated. Eventually, a cream containing as-synthesized Ag nanoparticles was produced using Rosa cannina extract through a green method. The data from the present research show that stable and spherical Ag nanoparticles were produced using different concentration of Rosa cannina extract which used as precursor. The findings proved that biosynthesis could produce natural cosmetic products like cream as a bio-friendly and cheap method.
